Abstract: An inpainting model which based on curvature driven oriented heat-flows is proposed in this paper.In this model，the diffusion toward the inpainting domain can be seen as the coupling of two weighted 1D heat flows along orthonormal directions.The diffusion directions are defined by the local coherence geometry of image and the diffusion strength is a function of curvature.Experimental results show that the emergence of artificial edges can be avoided and the sharp inpainting edges can be achieved by using this model.
